I have an older Spyder marker, the Elite model. I want to upgrade it with an expansion chamber, new bolt, regulator and a drop forward. I'm looking to drop around $300 into this marker. I already have a dye barrel attached, just looking for more performance enhancing accessories. If anyone can help, let me know. Thanks.

I would go with a regulator, clamping feedneck, on/off asa, maybe a barrel kit, freak, pipe, whatever you like. Electro Hopper, and an electronic frame if the Elite doesnt already have one. If it does, you can always upgrade to a Tboard and then add eyes.

as far as the regulator goes, which product is recommended? same for the electronic frame? And which bolt should I buy?

I've thought about buying a new marker, but i'm comfortable with this gun, and for what i want to spend, it would just get me a stock marker that i'd have to sink more money into. I'm not ruling it out down the line, but you know how it is when you are comfy with something that works well, its hard to get rid of.

I know what you mean... I dumped a bunch of money into my Spyder and love it.

I have the CP reg and it is very good. As for the E-Frame the ESP CAMD Frame is a good choice. You can go with any drop you like, just make sure the bottom matches the holes on your frame, or you can get an adapter. As for the bolt the ACS Bolt is a good choice, I have the Delrin one, but it is not necessary.
